Can someone please tell me I'm not going mad.

I have code attached to a 'cancel' button class to tablerevert any buffered tables open in the form. I have just accidentally bypassed this code and can't understand why I did not get an error code 1545 (table buffer contains uncommitted changes) when I click the cancel button. The table reverts without me doing anything. I've checked on VFP 6 and it is the same.

Did it always do this? Or in the distant past (e.g. VFP 3) did this cause an error 1545? I don't have a copy fo VFP 3 to check this on. I'm wondering why I put this code onto the 'Cancel' button if this never caused a problem.

.and given that VFP quite happily reverts the table itself when you close it, when would an error 1545 ever occur?
